As an experiment for a bigger project, I cooked up a simple program: It asks for integers interactively, and after each input, it spits out the running total. The wrinkle is that the function for calculating the total should be a non-monadic stream function (that is, type [Integer] -> [Integer] so that runningTotals [1,2,3,4,5] == [1,3,6,10,15]). The task is then to write a function to return a stream of integers, grabbing them from IO-land lazily (a la getContents).
Hi, what about module Main where main = getContents >>= mapM_ print . scanl1 (+) . map read . lines Happy hacking, Remi -- Diese Augen haben es gesehen Doch diese Augen schliessen sich Und ungehindert fliesst das Blut Und das Schweigen wird unertr�glich laut
